Definition
UV printing uses ultraviolet light to convert liquid ink into a solid film, which dries instantly through a photochemical reaction. This process is fundamentally different from traditional printing, which relies on natural evaporation or hot air drying. This article will explore the optimal use of full-screen UV and spot UV printing in various scenarios.
Full-screen UV and Spot UV
Process
Full-screen UV printing involves applying a uniform layer of UV ink to the entire printed surface. This is then instantly cured by UV light to form a solid protective film. This method requires no alignment and is ideal for rapid production.
Spot UV printing requires a printing plate, through which the UV ink is transferred to specific areas to ensure precise alignment with the design. Consequently, the spot UV printing process is more intricate.
Cost
Due to differences in technology, costs vary. Full-print UV coating doesn't require custom printing plates, resulting in a quick production process and relatively low cost, making it more economical. Spot UV coating, on the other hand, requires custom printing plates, leading to higher mold costs and demanding high precision and quality. This results in higher time and labor costs, ultimately leading to a higher overall cost.
Effects
Full-print UV coating covers the entire surface of the box with a durable, transparent protective film, primarily for waterproofing and wear resistance. Different types of varnish can achieve various effects: glossy full-print UV coating creates a uniform, mirror-like sheen, enhancing color saturation and making printed colors more vivid; matte full-print UV coating reduces glare and enhances the product's texture; and textured UV coating enhances the product's tactile feel.
Spot UV coating brightens specific areas and is often used in conjunction with matte film for a striking effect. Spot UV coating can also create a raised, textured effect that full-print UV coating cannot achieve.
Others
In terms of durability: Full-cover UV protection provides excellent protection by covering the entire product surface, offering superior scratch resistance. Spot UV protection, on the other hand, only protects the applied area, leaving the rest of the product exposed and failing to provide adequate protection for the entire product.
Summary
UV printing is widely used in the packaging industry due to its advantages. Its two main surface treatment methods—full-surface UV and spot UV—effectively meet the needs of most people. Full-surface UV is cost-effective and quicker to produce, offering protection and brightening effects; spot UV effectively attracts customers' attention and creates a premium feel for the product. Therefore, consumers can choose different processes based on their needs to achieve the best product effect.

FAQ
What is UV Printing and How Does It Work?
UV printing is an advanced technique that uses ultraviolet light to instantly cure special inks. Unlike traditional printing that relies on slow air drying, UV light triggers a photochemical reaction that converts liquid ink into a solid, durable film immediately upon contact.
What's the Difference Between Full UV and Spot UV Coating?
Full UV coating covers the entire surface with a uniform protective layer, providing complete scratch resistance and either glossy or matte finishes. Spot UV applies coating only to specific design elements, creating raised textures and striking visual contrast against uncoated areas.
Which UV Method is More Cost-Effective for Packaging?
Full UV coating is generally more economical as it requires no custom plates and enables faster production.
